HOLD ER FOR LAM P-GLOBES.

SPECIFICATION forming part of Letters Patent No. 439,090, dated October 28, 1890.

Application filed September 30, 1889. Serial No. 325,501. (No model.)

To all whom it may concern:

Be it known that I, ELIJAH ATKINS, a citizen of England,residing at Cherry Street, Birmingham, England, have invented a new and useful Holder for a Lamp Globe, Shade, or Like cArticle', of which the following is a specifica- This invention relates to the construction of holders for securing the globes, shades, or the like for gas, electrical, or other lamps, as will be described with reference to the accompanying drawings.

Figure 1 is asection, and Fig. 2 is a plan, of a holder according to this invention for securing a globe or shade which is provided with an outwardly-turned lip or flange. Fig. 3 is a section showing the holder applied to a globe or shade which hasno such flange or lip. Fig. 4 is a plan showing the catches of the holder retracted, and Fig.5 shows them protruded. Fig. 6 is a plan of one of the catches before it is bent. Fig. 7 is a side view, and Fig. 8 an end view of it when bent.

A is a socket,which may be stamped out 0 thin metal sheet and ornamented as desired.

13 is a ring made with two projecting arms I) b, which have their ends bent upward and riveted to the upper lip of the socket A, as shown at a, Fig. 1. At three points of the outer circumference of the ring B project guide-arms b, and at three points of its inner circumference tongues c of the sheet metal of which the ring consists are bent upward to form guide-studs for an upper ring D, which has three concentric slots in which the studs 0 are respectively engaged. The ring D has also an arm cl, that projects through a slot of the socket A, and outside A is bent into a round form, to which the fingers can 'be appliedto turn the ringD round through nearly one-third part of a revolution. The ringD is formed as a triple cam-that is to say, three parts of both its internal and external circumference are made eccentric to the slots in which the studs 0 are engaged, and each of those eccentric parts of D is embraced by a catch E, which is a piece of metal of the cross shape shown by Fig. 6, having an end limb e,which, as shown in Figs. 7 and 8, is bent upward in a rounded form, two side limbs e e, which are bent downward and inward, and another end limb e*, which is bent downward and backward. Thus the bent limbs e, e, and c are made to inclose and embrace the eccentric parts of the ring D and also the projecting guides 19' of the ring B. Then the globe or shade F has a lip or flange f, as shown in Fig. 1, the ring D, by applying the fingers tothe projecting part a,is turned partly round, so as to protrude the catchesE far enough to allow the flange f to be inserted within them, and then the ring D is turned backward, so as to retract the catches E, causing their upper bent limbs to engage over the flange f. When the globe or shade F has no lip or flange, as shown in Fig. 3, the catches E are first retracted, and the globe or shade F being inserted, they are protruded so that the bent parts e of the catches E engage over the inner edge of the globe or shade. The ring D is made to turn always concentrically with the socket, being guided by the engagement of the studs 0 in its concentric slots. The catches E are moved inward or outward by the eccentric parts of the ring D, and are prevented from moving round by their engagement with the guide-arms b of the ring B.

Having thus described the nature of this invention, and the best means I know of carrying the same into practical efiect,I claim- 1. Aholder for lamp globes, shades, or similar articles, consisting of the combination of a socket A,a ring B, secured therein and having guide-arms b, catches E, having limbs embracing and radially movable on said guides and adapted to hold the globe or shade, and a rotary ring D, having eccentric parts also embraced by said catches, substantially as set forth.

2. The combination of a socket A, a ring B, secured therein and having guides b and studs 0, catches E, bent to engage the globe or shade either outwardly or inwardly mounted and radially movable on said guides, and having studs 0 engaging said slots, and a rotary ring D, having eccentric parts engaged by said catches, and having circular slots engaged by said studs, substantially as set forth.

3. The combination of the part B, having lateral guide-arms b, catches E, having limbs e, embracing said guide-arms and having limbs e, adapted to hold a globe or shade, and limbs 6 and the rotary ring D,having eccentric parts embraced by said limbs e ,whereby the movement of ring D causes the radial sliding of the catches on said guide-arms,substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this l7th day of September, A. D. 1889.
